Habitat and population analysis for red-shouldered hawk, American bittern, and pileated woodpecker in the eastern Ontario pilot region. : En3-7/3-20E-PDF

"This report describes the habitat and population modeling and viability analyses we conducted for three species in the in Eastern Ontario Pilot Region: Red-shouldered Hawk, American Bittern, and Pileated Woodpecker. This project was in support of the development of biodiversity performance standards under the National Agri-environmental Standards Initiative. Our modeling approach is based on linking demographic and habitat models to estimate the viability, stability, and functionality of the metapopulation in the study area, based on the distribution, amount and quality of their habitat, and their demographic properties. The models were developed using RAMAS GIS, which links spatial data (such as habitat maps) to demographic data to simulate metapopulation dynamics with an age- or stage-structured model for each subpopulation. For each species, we describe the model in three sections: Demographic model, Habitat model, and Linking Habitat Model to Demography"--Executive summary, page x.
